Because it looks more like a ghostbusters ghost, I like the Wii version better, but the PC/PS3/X360 version is much more difficult. And if I'm reading the comments right, I prefer the non-Wii versions' story.

Yeah, it was a bit weird though the differences between the character in the Wii and other versions. I definitely liked this version from the Wii better, however in the Wii game Azetlor was an ancient Sumerian god of lost objects but at the same time the game claims he also was a human follower of Shandor and killed the Librarian.

In the more realistic game he was always a human before being elevated to a book golem of sorts, it seems.

It's east to get him to shoot those balls of books at you if you hide next to the bookshelves and close by him. It's a better spot then just scrambling around like cockroaches and constantly dodging his attacks... Also.... He looks more like a hag fish then a worm...
